It is narrated from Sayyiduna Jundub (may Allah be pleased with him) that he said: I heard the Messenger of Allah (peace and blessings be upon him) say: "When one of you asks permission three times and is not given permission, let him go back."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Yunus (may Allah have mercy on him) except al-Mughirah bin Muslim, and Shababah is alone in narrating it."
